Prince Silver Delivers Further Strong Drill Results, Highlighted by 7.62 Metres of 230 G/T Silver, 10.78% Manganese, 1.87% Lead, 2.54% Zinc and 0.58 G/T Gold

Executive Summary

• Prince Silver released robust assay results from RC drill holes PRC‑31 through PRC‑40, highlighting multiple high‑grade silver–gold–polymetallic intercepts across stacked stratigraphic horizons.
• Notable intercepts include:
• PRC‑37: 7.62 m @ 230.20 g/t Ag, 0.58 g/t Au (170.69‑178.31 m) and a deeper 25.91 m @ 28.85 g/t Ag, 0.95 g/t Au (245.36‑271.27 m).
• PRC‑31: 10.67 m @ 118.57 g/t Ag, 0.317 g/t Au (193.55‑204.22 m).
• PRC‑32: 4.57 m @ 223.67 g/t Ag, 1.91 g/t Au (144.78‑149.35 m) and a broader 21.34 m @ 32.09 g/t Ag (176.78‑198.12 m).
• The program now totals ~9,000 m of RC drilling; two rigs remain active with holes PRC‑47 and PRC‑48 underway, positioning the project toward a maiden NI 43‑101‑compliant mineral resource estimate.

Key Details

• PRC‑37 (Upper interval): 7.62 m @ 230.20 g/t Ag, 10.78 % Mn, 1.87 % Pb, 2.54 % Zn, 0.58 g/t Au (170.69‑178.31 m).
• PRC‑37 (Deep interval): 25.91 m @ 28.85 g/t Ag, 0.95 g/t Au, 1.02 % Zn (245.36‑271.27 m); within this, 9.14 m @ 1.73 g/t Au, 58.08 g/t Ag, 1.96 % Zn (251.46‑260.60 m).
• PRC‑31: 10.67 m @ 118.57 g/t Ag, 9.98 % Mn, 1.17 % Pb, 1.64 % Zn, 0.317 g/t Au (193.55‑204.22 m).
• PRC‑32 (Upper): 4.57 m @ 223.67 g/t Ag, 3.29 % Mn, 1.62 % Pb, 2.43 % Zn, 1.91 g/t Au (144.78‑149.35 m).
• PRC‑32 (Broad): 21.34 m @ 32.09 g/t Ag, 5.12 % Mn, 0.99 % Pb, 2.22 % Zn (176.78‑198.12 m).
• PRC‑35: 9.14 m @ 55.5 g/t Ag, 3.95 % Mn, 1.52 % Pb, 1.33 % Zn (233.17‑242.32 m).
• Step‑out holes: PRC‑38 terminated early due to faulting; PRC‑39 and PRC‑40 tested eastern limits of the Exploration Target, returning limited mineralization but helping define project boundaries.
• Program scale: Expanded RC program now ~9,000 m (31,000 ft). Two rigs continue drilling; next holes are PRC‑47 and PRC‑48. No anticipated stoppage in drilling activity.
• Historical context: Reinforces earlier January 13, 2026 highlights (e.g., PRC‑28: 3.05 m @ 1,331 g/t Ag). The Exploration Target (based on historic work) remains conceptual at 25–43 Mt with grades of ~38 g/t Ag, 0.30 g/t Au, 1.5 % Zn, 1.2 % Pb, 3.8 % Mn.
• Quality control: QA/QC program follows CIM and AUSIMM standards; duplicate samples, field standards, blanks, and independent laboratory verification employed. Primary lab: Skyline Assayers & Laboratories (ISO‑accredited).

Notable Quotes

“These latest results continue to highlight the exceptional scale, strength, and consistency of the Prince Silver Project's expanding mineralized system… With two rigs actively drilling and the program now expanded to approximately 9,000 metres, we believe the Prince Silver Project is continuing to demonstrate the characteristics of a large‑scale polymetallic discovery.” – Derek Iwanaka, CEO & Director
